The bankruptcy on 'Picking and textual content' is superb. the remainder of the chapters does a pleasant activity of winding up the creation to all components of a 3D game.

There are a few blunders too within the booklet - specially in bankruptcy three - the place we opt for the sting loop - the best way defined in bankruptcy didn't paintings for me, yet bearing on the Appendix on Blender helped. it's also really easy to wander away in the entire intricacies of Blender and C/C++, yet with a bit of of exploring it is simple to come back on course - endurance can pay off.
